Justification:
This species is endemic to Greece. The expansion of the cultivated areas and fire has played a role in the restriction of the species' populations and their local extirpation. According to Mylonas (1982, 1983), it was intensive grazing, and the subsequent impoverishment of the species' habitats that had the most significant impact of reducing population size. The species is extinct from most of the island previously present (now only known from subfossils) (Mylonas 1982, 1983). Currently, the area of occupancy is about 72 km2 and there is a continuing decline in any the (i) extent of occurrence, (ii) area of occupancy, (iii) the quality of habitat, (iv) number of locations or subpopulations, and (v) the number of mature individuals. This species is listed as Endangered B2ab(i,ii,iii,iv,v).

The species is endemic to Greece, being distributed in some of the Cyclades Islands (central Aegean), Rhodes and Astypalaia and some very small offshore islets. For most of these islands it is known from sub-fossils (Mylonas 1982, Mylonas 1983, Triantis et al. 2008).

There is an overall declining trend for the species' population. This species is extinct from most of the islands where it was previously present (now only known from sub-fossils) (Mylonas 1982, 1983).

The expansion of the cultivated areas and fire has played a role in the restriction of the species' populations and their local extirpation. Nevertheless, according to Mylonas (1982, 1983), it was intensive grazing, and the subsequent impoverishment of the species habitats that had the most significant impact.
